What you wanted to know about Hadoop, but were too afraid to ask: genealogy of elephants (New Year 2013).

About a year ago I have published the original genealogy of elephants. A number of changes have happened in the field since then and as some of my readers have pointed out the original diagram became stale. I am certainly thankful for the feedback and I am publishing the new version today. It sounds like a good New Year resolution too 😉

As you can see there are quite a bit of changes in the tree. Say, CDH4 looks like a child of promiscuous parents – not for the first time, apparently – as it inherits characteristics of H1 and H2 at the same time (MR1 if you wondering); and some other changes as well.
